 Has anyone configured some setup like that in Bridge mode (not ECMP)?

 I don't have access to any of the UBNT's we use right now, but any
 mode except WDS seems not to be fully L2 transparent,

standard 802.11 bridges *cannot* be L2 transparent, there isn't
space for enough MAC addresses without WDS.

 There's two WiMax Links to the same location, the idea is to use it for

 In a lab setup, OpenBSD Bridge directed connected on 3Com switch,
 everything works, no problem.

 My doubt is related with the LACP packets crossing the wireless links.

LACP is a link aggregation control protocol, it is *not* a keepalive
/ link failure detection protocol.

If you can move to L3 (routing rather than bridging) then ospf is
one way you could achieve something like what you want using OpenBSD
(failover + use bandwidth of both links when available via ECMP).
But you'll need either an L3-capable switch with OSPF support,
or a second box.

I don't have access to any of the UBNT's we use right now, but any
mode except WDS seems not to be fully L2 transparent, hence it might
be incompatible with trunks and  IPv6 doesn't work either. However,
WDS mode works just fine (tested on hundreds of devices, on network
with ca. 1300 users). Might help (doesn't do the stupid ARP proxying
crap).
